The following is a list of the commands that the server understands.
enable|disableservicegroupservicename
Enables/disables alerts for group and servicename. All disabled states are automatically saved to
the state file, which may optionally be re-loaded upon restarting or initial startup of the
server.
ackgroupservicecomment
Acknowledge a failure condition. This will store comment in the state of service (queryable by
doing a listopstatus command), and will surppress further alerts for the service. Once the
service returns to a non-failure state, then the acknowledgement is reset.
version
Displays the protocol version in the form of "version num" where num is the protocol version
number.
listaliases
Lists aliases.
listaliasgroups
Lists alias groups.
savestate
Save the state of the server. Currently, the only state which is saved is the
host/watches/services which are disabled.
loadstate
Load the state of the server. Currently, the only state which is loaded is the
host/watches/services which are disabled.
enable|disablehosthostname
Enables/disables host hostname in all groups. When the monitor is called, this hostname will not
be included in the list of hostnames sent to the monitor. If a group has only one hostname in it,
then the enable|disablewatch command should be used instead.
enable|disablewatchwatchgroup
Enables/disables an entire watch for watchgroup, as defined in the configuration file. Disabling a
watch not only stops alerts from happening, but it stops the actual monitor processes from being
scheduled.
reset Resets the server, forcing it to re-read the configuration file, kill off currently running
monitors, restart all monitoring, and reset all counters. This command is only accessible if
moncmd connects from the host which is running the mon server.
resetstopped
Resets the server and immediately stops the scheduler. This is an atomic version of the commands
reset and stop.
reloadauth
Reloads the auth.cf file in order to incorporate any new changes. The auth table is completely
re-generated; it is not merged.
resetkeepstate
If the word "keepstate" comes after the reset command, the server will do a "loadstate" right
after the reset, before the scheduler kicks back in.
stop Stops the scheduler, but continues to allow client connections.
start Re-starts the scheduler after it has been stopped.
testmonitorgroupservicename
Triggers a test for group and service immediately by setting the service's countdown timer to
zero.
test(alert|upalert|startupalert)groupservicenameretvalperiod
Triggers a test alert, upalert, or startupalert for group and servicename. retval is the integer
exit value to pass to the alert via the MON_RETVAL environment variable. You must also specify the
period as it appears in the configuration file. All alerts of the given type in that period will
be triggered, but the alert will not be logged.
servertime
Returns the current time of the server as seconds since Jan 1, 1970.
listgroupgroupname
Lists the members of group groupname.
listdescriptions
List the descriptions of each service, as defined in the configuration file. If a service
description is undefined, then it is not listed.
listalerthist
Lists the last alarms triggered for each service of each watch group, in addition to the summary
output. The number of alerts to keep in memory is bounded by the maxkeep variable, configurable on
the mon command line at startup, and expandable with the set command during runtime.
listfailurehist
Lists the last failures, in addition to the summary output. This is also limited by the maxkeep
variable.
listopstatus
Lists operational status of all services. Reports whether the last time a service group was tested
resulted in success or failure. The output is:
group service untested
group service time timeleft succeeded
group service time timeleft failed output
where output is the first line of output from the monitor script which failed, time is the time
that the condition was last noticed in time(2) format, and timeleft is the number of seconds left
until the service is tested again.
listsuccesses
Generates the same output as the listopstatus command, but only shows the services that have
succeeded the last time they were tested.
listfailures
Generates the same output as the listopstatus command, but only shows the services that have
failed the last time they were tested.
listdisabled
Lists all hosts and services which have been disabled by the disablehost|service command.
listpids
Shows the currently active watch groups/services along with their process IDs, and it process ID
of the server daemon.
listwatch
Lists all watches and services.
liststate
Lists the state of the scheduler.
setgroupservicevariablevalue
Sets a variable to value. Useful for temporarily changing an interval or alertevery value. Be
careful, because this can just set any value in the %watch hash, and some values that are
specified in the configuration file like "10m" or "35s" are converted and stored as just plain
integer seconds (e.g. "alertevery").
getgroupservicevariable
Displays the value of group service variable.
setvariablevalue
Assigns value to the global variable variable.
setopstatusgroupservicevalue
Sets the opstatus value for group and service.getvariable
Shows the value of global variable variable.
term Terminates the server. This command is only accessible if moncmd connects from the host which is
running the mon server.
